Rheumatrex is a prescription medication that contains the active ingredient methotrexate and is used to treat certain types of cancer, including leukemia, lymphoma, and breast cancer.

Rheumatrex is used in the treatment of severe rheumatoid arthritis, psoriasis, and juvenile rheumatoid arthritis.

Methotrexate, the active ingredient in Rheumatrex, is classified as an antimetabolite. It works by interfering with the growth of cancer cells and suppressing the immune system. In rheumatoid arthritis and psoriasis, it helps to reduce inflammation and control symptoms.

Use and Dosage

Read the Patient Information Leaflet if available from your pharmacist before you start taking methotrexate and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

Methotrexate is a strong medication. The dosage and how often you take this medication are based on your medical condition and response to treatment. There are many different dosing schedules for this medication (especially for cancer treatment). Taking this medication the wrong way may cause serious side effects, including death. You must follow your doctor’s instructions carefully. Take this medication by mouth as directed by your doctor.

For the treatment of psoriasis or rheumatoid arthritis, take this medication by mouth as directed by your doctor, usually once a week. It may take up to several months before you get the full benefit of this drug.

If you are using the liquid form of this medication, carefully measure the dose using a special measuring device/spoon. Do not use a household spoon because you may not get the correct dose.

Do not increase your dose or use this drug more often or for longer than prescribed. Your condition will not improve any faster, and your risk of side effects will increase.

Since this drug can be absorbed through the skin and lungs and may harm an unborn baby, women who are pregnant or who may become pregnant should not handle this medication or breathe the dust from the tablets.

Drink plenty of fluids while taking this medication unless your doctor tells you otherwise. Doing so helps your kidneys to remove the drug from your body and avoid some of the side effects.

How Does Rheumatrex Work?

Methotrexate, which is a Rheumatrex generic name, is a type of enzyme inhibitor. Methotrexate prevents specific enzymes from providing nucleotide synthesis and cell division, which in turn stops inflammation and abnormal cell growth.

What happens if I miss a dose?

Call your doctor for instructions if you miss a dose of methotrexate.

What happens if I overdose?

Seek emergency medical attention. An overdose of methotrexate can be fatal.

Overdose symptoms may include bruising or unusual bleeding, mouth sores, vomiting, little or no urination, bloody or tarry stools, or coughing up blood or vomit that looks like coffee grounds.

What to avoid?

Avoid drinking alcohol. It may increase your risk of liver damage.
